[Z06] Who's running Ferrea hollow stemmed exhaust valves? F2042P

Race Director
I have tried to read all of these valve-related threads to try to educate myself on the issue, and it seems that nothing is resolved except back and forth bickering. At times I have thought that Quick and Howie were the sane ones, Mark and Propain were just stirring the pot. Now, the more I read, I find myself thinking that Mark and Propain are the ones' making sense, and Quick and Howie are just causing trouble.
My point is, there are many new and some not-so-new members of the forum that have no clue what to think. It would be nice to just stay on topic without all of the other crap being thrown back and forth. Those long, quote-laden posts get old real quick when one is just trying to understand the valve problem. I think these four guys have a great amount of knowledge between all of them, and it would be great to see everyone get on the same page.

I think there's a very strong majority of members that has reached the same conclusion you describe in your first paragraph. Regarding the part of your second paragraph that I put in bold, I'm confident that there would be a nearly unanimous agreement to that. That's why he's probably the most "Ignored" person in this section, if not the entire forum. Just imagine how nice it would be if discussions could take place that are clean of the agenda based crap and the high need for validation of personal decisions.
Point made numerous times to no avail. Very telling about the individual, which speakes volumes.

Time for the mod's to close this thread. I will now be using the "Unsubscribe from this thread button" This thread was OK in the beginning but went down hill rapidly. I have a set of these valves and so far they seem fine. I guess the only answer here is wait and see. Time will tell.

Its not just the member that are tired of the back and forth bickering, its also the sponsors.
For you guys out there that are new to the LS7 world and stumble across these kinda of thread that you cant get answers out of, my recommendation would be to call, email or PM a trusted vendor/sponsor and get their take on the issue.
Here is our contact info: http://www.americanheritageperformance.com/Contact.html
Also just to reiterate the F2042P is a very good valve with great quality contorl. Ferrea has been making these hollow valves for years and years with great success both on the street and on the track.

I don't have a lot of expertise and never claim that I do. I do relate information from the proffessionals that I have relied on and know personally. I do contribute what I can about my personal experiences, mods, track video, etc. (you can search if interested) with 6 years of track time and 155K miles.
Since not all the experts agree then one must decide who to trust and what makes sense to them and allows them to drive their care with piece of mind. That is exactly what I have done. I am comfortable with my decision and the SS valves. If and when my professionals tell me there is something better than I will redo my heads again.
So you may find over time that your impression of which camp is more sane may change. I am hoping so

I don't like when someone decides that its time for all of us to quit discussions. When you are done then you are done. Untill there are two left wanting to continue the let it roll ..........
And you never know when someone will pop in with something interesting.

The thing is-----no one person has all the answers. Of course I believe GM does but that gets us no where. The "best" fix may not be known for some time while waiting on miles to accumulate, however there are several "fixes" that will work.

I'm not claiming "authority" here.
Nor am I holding myself out as any sort of "authority" here. Never have.
I am only a Corvette enthusiast and consumer like so many others in here, making my own observations and offering up my own opinions on those observations.
I'm just one of the common folk at the town meeting, which is this forum, asking questions and voicing concerns. Sometimes over some of the answers that I find peculiar.
I'm no "authority", and I claim no "authority". But I will offer my opinions on what some of the authorities say, and what I observe, just the same as other enthusiasts and consumers in here can and do.
Oh, and no disrespect taken.

You claim to be no authority or expert so it should be easy for you to understand why there is a possibility you might periodically ask questions which are irrelevant, dare I say stupid and thus not worth wasting time answering. There isn't necessarily some kind of conspiracy going on which it is your duty to uncover

It's pretty simple really. Limanar F'ckd up the post cast machine work on some unknown percentage of castings. There are two things to look for, as you could have one or the other, or both. 1) seat to guide concentricity 2) rocker pedestal location and /or height
1) is easier to fix with some good machine work on the seats. 2) is more difficult and costly. Easier to check for errors though. All you need is a sharpie. 2) doesn't effect those who run a stock cam, or cam with similar lift nearly as much as those running high lift cams either.
The rhetoric over the sodium, or two piece valves is complete rubbish. Just a smoke screen to confuse those who don't have a basic concept of valve train theory.
The rhetoric over PM guides is also complete rubbish. Powder metal is vastly superior to bronze alloys. It's just harder to work with than bronze and some cylinder head repair shops don't like to screw with it. It's also not as widely available, in as many different configurations as the bronze pieces, so once again, a PITA for shops.

IF there truly was a problem with the engineering of an in spec head and all its associated parts, you would never have guys like Jimman getting 188,000 miles without so much as ever pulling a valve cover.
IF a guy was truly concerned about the lack of heat conducting ability of air, that same guy would NEVER have strayed away from the OEM valve and become the main salesman for SS valves...well unless of course he was once again being intellectually dishonest.
You know I was thinking, that term "intellectually dishonesty" is very complimentary to a person, given that in the absence of it, all that remains is stupidity

But I believe that since this is a learning environment where many of us have the goal to learn, that we should leave no forum member behind.
There are however "stupid answers", and I believe yours to count among these..[/I][/COLOR]

Damn Paul, and I have been waiting for so long to give you a compliment. And you may have just given me a great idea.
I also know how you like keeping up with it, but the count is at 414 now.
